Brief Description: Riveting bottom inboard skin port wing - Part 1
Riveting of the bottom inboard skin on the port side begins. The wing walk area is tough so I used a number of blind rivets here. Most rivets can be reached thru the inboard rib holes or from the inspection access ports. Some require flexing the skin back and reaching in.
I put carpet strips in eavery bay to prevent damage from dropped bucking bars.
